Pharmaceutical formulation analysis using room temperature phosphorescence

Journal of Pharmaceutical and Biomedical Analysis, 1983
The large-scale production of tablets and capsules requires the presence of a variety of additives to complement the active ingredient, enhance the physical appearance of the dosage form, improve the stability of the formulation, or to assist the drug’s biological distribution [l].

Metal‐Metal‐π Interaction: A Pathway to Construct Organic–Inorganic Excited‐State and Supramolecular Assembly

Advanced Optical Materials, EarlyView.
An organic–inorganic mixed excited state is designed and demonstrated by combining the metal–metal and π–π interactions within a supramolecular Pt2–pyrene assembly. Directional orbital overlap between the Pt and carbon atoms gives rise to a long‐lived triplet emission, strong emission polarization, exciton–exciton annihilation, and efficient exciton ...

Mechanical Stretch α‐Cyclodextrin Pseudopolyrotaxane Elastomer with Reversible Phosphorescence Behavior

Advanced Science
Polyethylene glycol chains in two terminals of the naphthalene functional group are threaded into α‐cyclodextrin cavities to form the pseudopolyrotaxane (NPR), which not only effectively induces the phosphorescence of the naphthalene functional group by ...

Enhanced Energy Transfer from a Metal–Organic Framework to a Highly Confined Organic Phosphorescent Dye

Advanced Science, EarlyView.
A phosphorescent dye was designed to fit in a hand‐to‐glove fashion into the 1D‐pore channels of MIL‐68(In). We synthesized MIL‐68(In) as powder and thin films, loaded the dye into the pores with controlled packing, and found that the phosphorescence and quantum yield are enhanced.

Red Phosphorescence from Benzo[2,1,3]thiadiazoles at Room Temperature [PDF]

, 2016
We describe the red phosphorescence exhibited by a class of structurally simple benzo[2,1,3]thiadiazoles at room temperature. The photophysical properties of these molecules in deoxygenated cyclohexane, including their absorption spectra, steady-state ...

Bidirectional Photoswitching of a Tailored Azobenzene with Red and Far‐Red Light Involving Triplet Sensitization in an Aqueous System

Advanced Science, EarlyView.
The action spectrum of a tailored azobenzene is shifted toward bio‐optical window through the chemical modification of its singlet and triplet energy levels. Consequently, the bidirectional photo‐switching of azobenzene in physiological conditions is achieved when excited by red and far‐red light, which offers greater tissue penetration.

Matrix‐free room‐temperature phosphorescence graphitic carbon nitride quantum dots based on halogen bond interactions for security applications

Nano Select, 2022
Herein, we first designed a one‐step strategy to achieve matrix‐free room temperature phosphorescence (RTP) materials by low temperature solid phase synthesis, using sodium citrate as carbon source and urea as nitrogen source.

Antenna Effect in Halogen‐Containing ZnSm Coordination Compounds: Utilizing Colorimetry for a Room‐Temperature Tunable Ratiometric Molecular Thermometer

Advanced Science, EarlyView.
The ZnSm‐Cl dinuclear molecular complex was synthesized through a simple one‐pot method. ZnL and Sm3+ exhibit complementary temperature‐dependent emission As the temperature increases, a noticeable color difference of ZnSm‐Cl can be observed within the room temperature range of 253‐333 K.

No role for muons in the DAMA annual modulation results [PDF]

, 2012
This paper gathers arguments and reasons why muons surviving the Gran Sasso mountain cannot mimic the Dark Matter annual modulation signature exploited by the DAMA/NaI and DAMA/LIBRA experiments.
